.port to prevent se aration of the su ports and the drawer. his roller17 is prefiirably arranged near the center of the drawer in order thatit may sustain most of the weight thereof, a staple or projection 20being provided near the rear of the drawer on either side thereof tooperate in the longitudinal grooves 21 of the corresponding supports toL, prevent tilting of the drawer.

Forward motion of the drawer relatively 'to the'supports 9 is limited bythe cooperatively-arranged aliutments 22 and 23,ar ranged, respectively,on the drawer and on the supports, and forward motion of theextension-supports relatively to the casing is limited by the relativelyfixed abutment 24,

' which is arranged, preferably, on the guides 3 in such a position astocooperate with the bracket 12, which carries the roller 13 of the willmove in a straight line and cannot sag as it approaches the forwardlimit of its motion, as the rear ends of the movable supports aresuspended by the rollers 13 and the forward portions are supported bythe rollers 8, while the rollers 11, running on the lower track 5 of theguides, prevent the forward ends of the supports from tilting downward,the series of guiding-tracks thus formed positively limiting thevertical motion of the parts, and

by means of the guiding-grooves in the guides and supports lateraldisplacement of the various parts is positively prevented, unless thedrawer is lifted out of its normal osition between the movable supports,and this will allo'w'the parts to be removed from the casing; butnormally thedrawer will serve to pre vent displacement of the movablesupports and will in turn be guided between them.

In withdrawing the drawer from the. easing the drawer and supportsusually move forwardly bodily until the brackets 12 of the sup ortsengage the stops or abutments 24 of t ecasin when the forward motion ofthe supports will be arrested and continued motion of the drawer willcause the latter to move forwardly on the supports until'the abutments22 of the drawer cooperate with the corresponding abutments 23 at theforward ends of the supports, and at this point the drawer and thesupports are at the limit of their forward motion. 'In returning thedrawer to the casin the front board of the drawer, which usuall yprojects from the sides thereof, will engage the forward ends of thesupports after the drawer has moved rearwardly-thereon and continuedmotion of the parts rearwardly will cause the drawer and supports to bereturned bodily into the easreceive the guiding devices considerable sace is economized, so that the sides of the d i'awer may fit veryclosely within the casing, as the supports require a very narrow spacein which to operate.

In providing a rolling en a ement for the relatively movable parts oi te device friction and wear are positively eliminated, and thereforedrawers equipped with supporting means embodying my invention will fit Eclosely within their casing and will not bind from warping and similarcauses, and as the guiding-tracks form a series of ways which willpositively prevent relative vertical motion between the parts and theguidingdrawer and its parts are insured at all times.

I claim as my invention- 1. The combination with a casing having adrawer-receptacle therein, a drawer adapted to operate in the rec-etacle and horizontal ways on the casing, o sliding supports for thedrawer arranged to operate beneath said ways and having bearings uponopposite sides of the ways.

2. The combination with a casing having a drawer-receptacle therein, adrawer adapted to operate in the receptacle and guides on the casing, ofsliding supports for the drawer having rollers operating on tracks uponopposite sides of the guides.

3. The combination with a casing having a drawer-receptacle therein, adrawer adapted to operate in the receptacle and guides on the casing, ofa pair of sliding supports arranged between the sides of the drawer andthe casing, having rollers engaging the upper sides of the guides, androllers arranged at the front of the receptacle and bearing on the undersides of the supports.

4. The combination with a casing having a drawer-receptacle therein, adrawer adapted to operate in the receptacle and ways on the casing, ofsliding supports for the drawer guided by said ways and having grooveson their under sides, rollers arranged at the front of the receptacleand bearing on the under sides of the supports and means cooperatingwith the grooves'in the sup orts for preventing lateral displacement oft e latter.

5. The combination with a casing having a drawer-receptacle therein, adrawer adapted to o erate in the recepltacle, guides on the easing avinggrooves t erein, and sliding su ports for the drawer having grooves on te 6, 14, and 19 in the guides and supports to rooves and their 006crating parts limit the ateral motion thereo proper operation of the i55' cured to the casin having upper and lower see,
